Petit Poll

Petit Poll Petit Poll combines data from small surveys with statistical methods to generate meaningful results. Collating these large samples is costly and time-consuming.

We are able to gain an understanding of opinion on a regular basis because smaller surveys have lower costs. A traditional poll needs a large sample because it attempts to replicate a population. Petit Poll overcomes this challenge by using small, non-representative samples combined with demographic and other data. We then use statistical models to 'scale up' the samples to provide representative

results for the population. Petit Poll augments traditional polls, such as Roy Morgan, Newspoll, Galaxy, etc, with frequent micro-sampling to produce rapid feedback at critical moments. Petit Poll's statistical approach is developed in Wang, Rothschild, Goel and Gelman (2014). Our specific implementation of the model (written in R using JAGS) will be made available soon.

While we use Cloudflare, no survey responses were collected via the website during the period of the bug (based on the information they released today).

We'll need to adjust our processes going forward and will put some thought into this as part of the current revamp.

If you have any concerns/suggestions please do get in touch.

We're working on improving our logo. What do you think?

First look at the outer parallelogram, then look at the larger and smaller inner parallelograms, denoted by red and blue triangles. Notice that the blue and red inner parallelograms are similar to each other in terms of the angles? Notice that they are similar to the outer parallelogram?

It's a similar idea to what we do with Petit Poll - using information we collect on a small sample, and the knowledge that it is related to a larger sample to help understand the broader implications.

The original image is from Euclid, Elements of Geometry, Book VI, Prop XXIV, c. 300 BCE. It was colored in this manner by Oliver Byrne in 1847 and republished by Taschen in 2013.

Others can discuss elsewhere the broader implications of Brexit. I want to make a few brief points about the Brexit polling. The polls were about as accurate as I'd expect. Mostly they reported that the referendum was going to be close. Generally, their interval of expected outcomes included the cri...

Who do you trust? http://www.petitpoll.com/blog/2016/6/22/who-do-you-trust

This is the first in a series of posts analyzing tweets about the election. What do you remember about the 2004 election? Perhaps it was the Howard-Latham handshake, the worm, or Medicare Gold. I remember Howard making the election about trust.  ...Who do you trust to keep the economy strong and pro...

Model updates http://www.petitpoll.com/blog/2016/6/13/model-updates

We use a multilevel regression and post-stratification (MRP) approach to obtain estimates of voting intent. Our approach closely follows the approach used by Ghitza and Gelman (2013). However, this week we made some changes to the underlying model, to better make use of the information obtained from...

Our database http://www.petitpoll.com/blog/2016/6/10/our-database

Petit Poll uses biased samples. Traditionally, this would make our results meaningless, but we are able to make reasonable conclusions because we tie our samples to representative data. The best option for this representative data would be a large exit poll from the 2013 election. But, I was not abl...

We had 60 responses to a quick, fun, Twitter poll. The expected election result on 2 July was essentially even.

The result was unexpected because the poll was targeted toward people likely to support the ALP (based on location and interests). Will re-do next week trying to target likely-Coalition supporters.

Unless you live in Canberra you are unlikely to be exposed to our Facebook/Twitter ads. So I thought I'd take a moment to show you what they look like. Our current Facebook/Twitter ads look like this: They (hopefully) draw a viewer in with the photo, and then ask a question about the photo. For thos...
